Abstract: Abstract of the Disclosure A high definition color television picture signal is unified by the time-axis compressed integration (TCI) and the bandwidth thereof is extremely narrowed by the dot-interlace subsampling.  As a result, a narrow band  transmission picture  signal accompanied with a control signal adapted to the restoration of the received original picture signal, which is suitable for the  satellite broadcast,  can be obtained through a comparatively  simple  arrangement.   The received narrow band transmission picture signal can be restored by  the  interpolation  adapted respectively to the stationary picture and the motional picture under the control of the control signal or the picture-motional information detected from the received picture signal with the reinforcement of the control signal, so that the  original high definition can be sufficiently maintained through a comparatively simple receiving equipment.

Abstract: Abstract of the Disclosure A separation process has been found in which a polymer-solvent solution separates into phases of highly different composition which are in equilibrium over a broad temperature range.  Upon addition of the phase sepa-rating agent, which is near or above its supercritical con-ditions, rapid disengagement into two phases occurs.  The relative volume of solvent rich phase is substantially lar-ger than the polymer rich phase.  The process can be prac-ticed at relatively low temperatures such as those em-ployed in polymerization or post-polymerization processes. The separation is accomplished by adding or elevating the concentration of a phase separation agent to or above a minimum effective concentration, which causes the UCST and LCST lines to merge.  Suitable phase separating agents are organic and inorganic compounds that are gases at 1 atm pressure and 25°C.  Due to the gaseous nature of the phase separating agent, it is easily removed from the solvent phase for reuse in the process.

Abstract: MULTI-STAGE ECHO CANCELLER     Abstract of the Disclosure In an echo canceller for use in full duplex, two-wire, digital transmission systems, satisfactory operation at higher bit rates (>144 Kb/second and above) is achieved by at least two adaptive filter stages operating in tandem.  In preferred embodiments, each stage comprises a random access memory (RAM), a digital/analogue converter and differencing means.  In each stage, each sequence of bits in the transmitted signal address the RAM which outputs a corresponding digital word to the digital/analogue converter.  The corresponding analogue signal from the digital/analogue converter is subtracted from the received signal.  The difference signal so obtained is used to update the digital word in the RAM so as to approximate the echo more closely when the particular sequence recurs.  The second stage digital/analogue converter has an output range much smaller than that of the first stage, preferably about equal to the minimum gradation of the first stage digital/analogue converter.  Consequently the first stage performs coarse cancellation of the echo and the second stage then further reduces the residual.          To enable such further reduction, the updating of the RAM in the first stage is "frozen" once that stage has converged.     - i -

Abstract: ABSTRACT     Safety closures resistant to (and evidencing) tampering comprising a snap cap or screw cap, a rotary safety ring, and a locking member, usually located below the rotary safety ring, said closure requiring that the locking member be removed before the safety ring can be lowered; the safety ring must be aligned with the cap in one angular position and pushed downwardly away from the cap before the cap can be removed from the container (i.e. "opened").  The locking member (e.g., either a second ring or a tear strip) includes a first engaging means (e.g., inwardly directed teeth) which engages a second engaging means (e.g., outwardly directed teeth) located on the neck of the container to which the safety closure is attached.  The locking member, prevented from rotation by the engagement of the first and second engaging means, is attached to the rotary safety ring by a connection, which should be broken whenever the closure has been tampered with.  The connection may be a fragile tear pin, designed to break when a sufficient rotary force is applied to the rotary safety ring, or a peel pin, being resistant to breaking when said safety ring is rotated relative to said locking member but allowing said locking member to be peeled from said safety ring.  A tamper resistant and tamper evident safety closure comprising a snap cap, capable of being removed only when a thumb tab extends past an annular ridge, that engages (via, e.g. a peg or a breakable arm) a snap off ring that is prevented from rotating by engaging the annular ridge; the breakable arm or peg evidences (and resists) the tampering.  A tamper evident and tamper resistant safety closure comprising a snap cap (or a screw cap) and a rotary safety ring and a cylindrical sheath, being peelably attached to the safety ring and preventing the safety ring from being lowered as long as the sheath is between the safety ring and a circumferential shoulder.

Abstract: ABSTRACT: "Fast method and device for determining an NMR distribution in a region of a body"            The invention relates to a method of making NMR images (density distributions, location-dependent spectroscopy) utilizing two alternating gradient fields whose gradient directions are mutually perpendicular. Thus, a two-dimensional "plane" in the 3-D image frequency space can be filled with a uniform density of measurement points. Per FID signal more signal samples can be taken, resulting in a substantial reduction of the entire measure-ment procedure for a 3-D image. This method is very well suitable for the imaging of 3-D density distributions, 2-D or 3-D spectro-scopy etc. The periods and the amplitudes of the alternating gra-dient fields are preferably the same; however, these fields are preferably phase-shifted 90° with respect to one another.
